B. Remote Voltage Sensing Leads Placement Guidelines For A Single Arc (Required)
Ref. 804 108-A
BEST
Sense leads are out of the current
paths.
Sense leads detect arc voltage ac-
curately.
Best starts, arcs and most reliable
results.
BAD
Sense lead is affected by weld
current.
Due to voltage drops across work
piece, arc voltage may be low,
causing need for deviation from
standard procedures.
